Justification:
Listed as Endangered because its extent of occurrence is less than 200 km², all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat. Field surveys are needed to determine whether or not it occurs elsewhere on the island.

This poorly-known species is endemic to Fergusson Island, of the D'Entrecasteaux Islands, Papua New Guinea. All records are from the mountains in the west of the island at elevations of 600 to 1,000 m asl; it is possible that the species is restricted to this area (Flannery 1995).

The species is not known from any protected areas. Further field studies are needed to better determine the distribution (particularly to see if it is present elsewhere on the island), abundance, and threats to this little-known species.
